It is shown within the framework of the ab initio statistical mechanics that the triple defect formation is not the dominant thermal excitation in stoichiometric B2-FeAl, at least at low temperatures. Therefore the customary type or analysis of magnetic susceptibility measurements exclusively in terms of triple defects may yield erroneous results for the concentration of Fe vacancies.
